Girovac Ltd


The PHOENIX L300i is a portable multi-purpose helium leak detector and equally well suited to both service and serious productio testing. The rugged modular design and its ease of use make the PHOENIX L300i one of the most user-friendly leak detector in its class. Through the remote controls tablet and RC310, remote monitoring and control is possible.

  • Lowest detectable leak rate
  • Short Helium recovering time condition
  • Quick startup under 2 minutes
  • Extremely fast response time
  • One of the smallest helium detectors in the world
